The Rocky Mountain Locust Plague of 1875

A swarm of Rocky Mountain locusts streams overhead for five days, creating a living eclipse of the sun. It is a superorganism composed of 10 billion individuals, devouring as much vegetation as a massive herd of bison — a metabolic wildfire that races across the Great Plains. Before the year is up, a vast region of pioneer agriculture will be decimated and U.S. troops will be mobilized to distribute food, blankets and clothing to devastated farm families... By clocking the insects’ speed as they streamed overhead, and by telegraphing to surrounding towns, Dr. A.L. Child of the U.S. Signal Corps estimated that the swarm was 1,800 miles long and at least 110 miles wide.
On 'grasshopper glaciers' and the lessons learned from the mysterious disappearance of a plague of biblical proportions.
